Rutgers School of Public Health student, Bryan Balarezo, spends several hours a week assembling and packaging fecal immunochemical test (FIT) kits, which are mailed to patients for at-home use. The kits test for hidden blood in stool, which can be an early indicator of colorectal cancer or other abnormalities. If a FIT result is positive, the patient is referred for a follow-up colonoscopy to determine the cause of the abnormal result.
